T-Mobile has accomplished a milestone by becoming the world’s first network operator to launch a commercial nationwide standalone (SA) 5G network. This accomplishment allows the company to expand its 5G footprint and bring the next-generation mobile network’s speeds to more markets.

The move, which was made possible through the company’s acquisition of Sprint, immediately expands T-Mobile’s 5G footprint by 30% to cover more than 7,500 cities and towns across the US. It also allows the company’s 5G network to penetrate deeper into buildings, improving the network's reliability.

In a press release, T-Mobile’s President of Technology, Neville Ray, stated, “Since Sprint became part of T-Mobile, we’ve been rapidly combining networks for a supercharged Un-carrier while expanding our nationwide 5G footprint, and today we take a massive step into the future with standalone 5G architecture. This is where it gets interesting, opening the door for massive innovation in this country — and while the other guys continue to play catch up, we’ll keep growing the world’s most advanced 5G network.”

Let’s meet the team that vaulted T-Mobile to the front of the race for nationwide 5G.

Ulf Ewaldsson joined T-Mobile in January 2019 and is the driving force behind the company’s 5G technology evolution strategy. He serves as the company’s Chief Network Officer and has been instrumental in plotting the company’s 5G rollout as it integrates a slew of low- and mid-band spectrum from Sprint.

John Saw, is the Executive Vice President of Advanced and Emerging Technologies at T-Mobile and is responsible for the company’s future technology product and services roadmap. Saw and his team set the company’s strategy for new products that improve customers’ lives. Prior to joining T-Mobile, Saw was the Chief Technology Officer at Sprint, which has likely made him indispensable as they integrate Sprint’s 5G technology into T-Mobile’s network.

Karri Kuoppamaki is T-Mobile’s VP of Radio Network Technology Development and Strategy. In this role, Kuoppamaki oversees the development of the carrier’s Radio Access technology, which powers its 5G network. He is also responsible for maintaining alignment between T-Mobile’s radio technology and spectrum policy and the regulatory environment. His work has ensured that the company didn’t suffer regulatory setbacks as it proceeded to launch its nationwide SA 5G network.
